Chrissy LeMaire gives us several ways to format file sizes with dbatools:
Within dbatools, you may notice file sizes are pretty and human-readable.
That was some C# based magic created by Microsoft PFE and creator of PSFramework, Fred Weinmann. In the background, SQL Server often gives us different types of numbers to represent file sizes. Sometimes it’s bytes, sometimes it’s megabytes. We wanted to standardize the sizing in dbatools, and thus the
dbasizetype was born.
Human-readable file sizes are great but they make it difficult to compare when piping sets of data to Format-Table. Knowing how to override this when necessary gets you the best of both worlds.
